How would complete melting of the Greenland Ice Sheet affect global sea level?

If the Greenland Ice Sheet were to melt completely, it is estimated that global sea level would rise by approximately 24 feet (7.4 meters).1

While some climate models suggest that an additional 2 °C (3.6 °F) of warming could lead to the ultimate destruction of the ice sheet, the timing of such an event remains a subject of study, with some projections indicating it could take several centuries. Such a significant rise in sea level would have profound consequences for the global environment, as it would submerge many low-lying coastal regions and threaten heavily populated cities worldwide, including New York, Tokyo, and Mumbai.2
